摘　　要：用含Ｓ夸克压低约化机制的事件产生器ＬＵＣＩＡＥ研究了相对论性核一核碰撞中青异增强现象，ＬＵＣＩＡＥ结果和相应的ＮＡ３５实验数据符合得较好．结果还表明：ｓ夸克压低约化在奇异产生物理中的作用要大于再散射．We use the event generator LUCIAE with the mechanism of reduction of strange quark suppression to investigate the strangeness enhancement in relativistic nucleusnucleus collisions. The results of LUCIAE reproduce the corresponding NA35 data quite well and explain very well that the reduction of strange quark suppression plays more important role than the rescattering of final state hadrons in the production of strange particles.
